UK rules
As of 2023/24, you’re entitled to an annual tax-free gift allowance of £3,000. This is also known as your annual exemption. With your annual gift allowance, you can give away assets or money up to a total of £3,000 without them being added to the value of your estate.
If you don’t use your full gift allowance in one year, you’re allowed to roll it over to the following year. You’re only allowed to do this once, so you couldn’t roll any allowance you haven’t used over for a second year.
Once you’ve exceeded your annual tax-free gift allowance, the gifts you give may be subject to inheritance tax in the event of your death. However, this only applies if you die within seven years of giving a gift (more on this later). If you live for longer than seven years after giving the gift, no tax is payable (unless it’s part of a trust).
